Hi I’m new member here 👋🏽

I’m getting what looks like oil coming out of the end of my exhaust...
Can anyone help me with ideas of what could cause this please?

Could it be the PCV valve? 🤔

No smoke, other than usual when cold.

Had car at garage to get spark plugs & oil filter change last week & the garage said one of my spark plugs look a wee bit black. They also said engine looks well etc

Any help what be much appreciated.
Thanks
